India–South Korea has become a genuinely popular route over the last few years, driven partly by K-pop tourism and partly by the growing Indian diaspora doing Seoul for the first time. The route is well-served enough that you have real options — direct on Air India from Delhi, or connecting through Bangkok or Singapore for potentially significant savings. Here's everything you need to know to book it smartly.
TL;DR — How to Book Cheapest India–South Korea Flights
Direct flights from Delhi (DEL) to Seoul Incheon (ICN) on Air India are convenient and increasingly competitive in price, but one-stop options via Bangkok or Singapore typically come in around 20–40% cheaper when booked outside peak periods. Economy returns on connecting routes can often be found in the ₹30,000–45,000 range; direct routes typically run ₹45,000–75,000+ return in economy. Best months are March–April (before summer) and late September–October (after Chuseok holiday crowds). And don't forget: Indian passport holders need a K-ETA (Korea Electronic Travel Authorization) before arriving — it's not expensive or difficult, but you must apply in advance. More on that below.
Direct Flights from India to Seoul: What's Available
The primary direct service from India to Seoul Incheon (ICN) is Air India from Delhi (DEL). Air India's widebody aircraft serve this route, and the product has improved meaningfully post-Vistara merger — the combined Air India now has access to former Vistara narrowbodies for domestic connections plus the widebodies for long-haul routes like this one. Check Air India's route map and schedule at airindia.com for current frequency and aircraft type on your dates — schedules do change seasonally.
Korean Air and Asiana Airlines have also served the India–Seoul route at various points, though Indian feed connectivity varies. It's worth checking both on a metasearch alongside Air India — sometimes Korean carriers have pricing that competes on the direct routing.
From cities other than Delhi, you're connecting regardless. Mumbai (BOM), Bangalore (BLR), Hyderabad (HYD) and Chennai (MAA) all have excellent domestic connections into Delhi, which then positions you for the nonstop to Seoul. Some travellers prefer to connect internationally directly from Mumbai or Bangalore (via Singapore or Bangkok) rather than routing through Delhi domestically — this can make sense if the direct-to-hub-to-Seoul itinerary is cheaper than the domestic-then-international combination.
Connecting Routes: Bangkok, Singapore, and Beyond
For most Indian cities outside Delhi, connecting via a Southeast Asian hub is the default way to reach Seoul. The main options:
Via Bangkok (BKK): Thai Airways, Korean Air via Bangkok, and other carriers. Bangkok–Seoul Incheon is a very well-served sector — lots of frequency, which means more fare options. Thai Airways' connecting product is comfortable. Total journey time from most Indian cities: typically 13–17 hours depending on connection timing. Economy return fares on India–Bangkok–Seoul itineraries are often in the ₹28,000–45,000 range, sometimes lower on LCC combinations.
Via Singapore (SIN): Singapore Airlines and their subsidiary Scoot both fly Singapore–Seoul. Singapore is a strong transit hub — good connections, reliable operations, short enough airport to minimise stress. From Mumbai or Bangalore to Singapore on IndiGo or Air India, then Singapore Airlines onward to Seoul is a common and reliable combination. Economy return fares on this routing: roughly ₹32,000–50,000 return, depending on carrier and timing.
Via Kuala Lumpur (KUL): AirAsia and Malaysia Airlines both operate KL–Seoul. The cheapest India–Seoul fares I've seen have often been on KL-routing combinations, particularly during AirAsia sales. Total fare including checked baggage and meals (non-negotiable if you're packing for Seoul's shopping-friendly streets) can still come out below what direct routes cost.
Via Hong Kong or Guangzhou: Cathay Pacific and China Southern also connect Indian cities to Seoul via their respective hubs. Worth checking if Southeast Asian hub prices are high on your dates.
Price Comparison: Direct vs Connecting in 2026
Here's a rough picture of the price landscape as of 2026, based on patterns I've tracked. These are ranges, not guarantees — fares shift constantly and the gap between direct and connecting varies significantly by booking timing and travel dates.
- Direct (DEL–ICN) economy return: Typically around ₹45,000–75,000 outside peak seasons. During cherry blossom (late March–April) or autumn colour (October) or around Diwali/Chuseok holidays, can run higher. Air India sales and last-minute availability can occasionally bring this lower.
- Connecting economy return: Often in the ₹28,000–48,000 range via BKK or SIN, sometimes lower on LCC combinations via KL. The saving is real and consistent, but narrows during Air India flash sales.
The practical calculation: if you're going for 7–10 days and value your time, paying ₹10,000–15,000 more for a nonstop that saves 4–6 hours each way might be worth it. If you're going for 2+ weeks and budget flexibility matters more, the connecting fare saving is enough to cover several nights of accommodation in Seoul.

Best Months to Fly India to South Korea
Seoul has real seasons, and both fares and tourism intensity follow them. Here's the honest breakdown:
- March–April (cherry blossom): Beautiful but busy and pricey. If cherry blossoms are the point of the trip, book 2–3 months ahead minimum. Late March and first week of April tend to be peak-within-peak.
- May–early June: Shoulder season. Warm weather, fewer crowds than cherry blossom, fares more reasonable. One of the underrated times to visit.
- Mid-June–August (summer): Hot, humid, and busy with Korean domestic tourists. Fares can spike around school holidays and Chuseok (Korean harvest festival — date varies, check the year's calendar). Budget travellers often find this period disappointing on both fronts.
- Late September–October: Autumn foliage season. Similar situation to cherry blossom — beautiful, popular, pricier. But the fares aren't as extreme as April peaks if you avoid the Chuseok holiday window itself.
- November–February: Cold. Seoul winters are proper cold — think Delhi in January but longer. Fares tend to be at their lowest (outside Christmas/New Year) and the city is genuinely enjoyable if you dress right. This is when I'd go if budget is the primary concern.
K-ETA: The Entry Requirement You Cannot Forget
As of 2026, Indian passport holders require a K-ETA (Korea Electronic Travel Authorization) to visit South Korea for tourism — it replaced the previous visa-free arrangement for short stays. The K-ETA is applied online through the official K-ETA website (k-eta.go.kr — always use the official government site, not third-party services that charge extra for the same thing).
The K-ETA is not a visa — it's an electronic travel authorisation similar to Canada's eTA or Australia's ETA. Processing is typically within 72 hours, though the official site recommends applying at least 72 hours before departure. The authorisation is valid for multiple entries over a set period (check the current validity period on the official site — it has changed before). The fee is modest — check the current amount at k-eta.go.kr before applying.
Important: the K-ETA has specific eligibility conditions and some travellers have been found ineligible, in which case they'd need to apply for a proper visa at a Korean consulate. Check eligibility on the official site before booking. And carry a printed copy or clear screenshot of your K-ETA approval to show at immigration if asked.

Booking Window and Practical Tips
My recommended booking window for India–Seoul economy fares is 6–10 weeks before travel for connecting options, and 8–12 weeks for nonstop Air India fares if a specific date matters. Booking more than 3–4 months ahead on this route doesn't consistently produce lower fares — airlines don't release their cheapest inventory that far out on most routes.
A few practical notes for first-time India–Korea travellers:
- Currency: South Korean Won (KRW). ATMs are widely available and give decent rates. If you're carrying a zero-markup card like Scapia or IDFC FIRST, it works at Korean ATMs and shops with no forex fee. Cash is still used in some traditional markets and smaller restaurants.
- T-money card: Get one at Incheon airport on arrival — it's a reloadable transit card that works on Seoul metro, buses, and even some taxis. Much more convenient than buying single tickets.
- Seoul vs rest of Korea: Most India–Seoul flights land at Incheon (ICN), not Gimpo (GMP). ICN is 60–70 minutes from central Seoul by AREX express train (highly recommended over taxis for the first trip).

Frequently asked questions
Is there a direct flight from India to South Korea?
Yes — Air India operates direct flights from Delhi (DEL) to Seoul Incheon (ICN). Korean Air has also served Indian cities at various times. From other Indian cities (Mumbai, Bangalore, Hyderabad, Chennai), you'll typically connect through a hub. Check Air India's current schedule on airindia.com for direct service details — frequency varies seasonally.
Do Indian passport holders need a visa for South Korea in 2026?
Indian passport holders need a K-ETA (Korea Electronic Travel Authorization) for tourism visits as of 2026 — this replaced the previous visa-free arrangement. Apply via k-eta.go.kr (the official Korean government site) at least 72 hours before departure. The K-ETA is not the same as a visa — it's an electronic authorisation. Some travellers may find they need a full consulate-issued visa depending on their eligibility; check the official site first.
What is a realistic budget for India to Seoul flights in economy?
Connecting economy returns can often be found in the ₹28,000–48,000 range during off-peak months (November–February, May, late September) when booked 6–10 weeks out. Direct Air India economy returns typically run ₹45,000–75,000 outside peak seasons. Cherry blossom season (late March–April) and autumn foliage (October) push prices up significantly on both direct and connecting fares. Always check current fares — these ranges move with demand.
Which is the best month to visit South Korea from India?
March–April (cherry blossom) and September–October (autumn foliage) are the most popular and visually stunning but also the priciest and busiest. May and late September are good shoulder-season compromises. For the cheapest fares and fewer crowds, November to February (excluding Christmas–New Year week) is the optimal window, though Seoul winters are genuinely cold.
How do I apply for K-ETA from India?
Apply at the official K-ETA site: k-eta.go.kr. You'll need your passport details, travel dates, accommodation information, and a recent passport-size photo. The fee is modest (verify the current amount on the official site) and processing is usually within 72 hours. Apply at least 3–5 days before travel for buffer. Avoid third-party 'K-ETA service' websites that charge extra fees — the official site is straightforward and the only authoritative source.
Is it cheaper to fly to Seoul via Singapore or via Bangkok from India?
It depends on your origin city and travel dates. Bangkok (Suvarnabhumi) generally produces the cheapest India–Seoul fares in the aggregate, particularly on Thai Airways and combination LCC bookings. Singapore (Changi) is often slightly more expensive but offers a more comfortable transit experience and higher connection reliability. From Mumbai or Bangalore, Singapore is often the more natural transit hub. Use a flexible-dates metasearch on your specific origin city to compare both routings on the same search.
